編集：ディスクアプリで私はこれを見つけました：
私が試した別のこと：

Capacity 128 GB 64 GB 32 GB 16 GB 8 GB 4 GB
Generation USB 2.0 USB 2.0 USB 2.0 USB 2.0 USB 2.0 USB 2.0
USB2デバイスである必要があります。だから、USB3ポートでバグがある可能性があります
usb 3-6: reset high-speed USB device number 9 using xhci_hcd
...
usb 3-6: new high-speed USB device number 10 using xhci_hcd
別のUSB2ポートに変更します。ラップトップには既に2つのポートが必要です（ Lenovo ThinkPad T440p spec。 ）。

オプション1. BIOSからUSB3を無効にします

- USB3としての左側2
- 2右側、USB（？がある場合
+USB2であることを示す署名） BIOSには、USB2とUSB3の間の2つの共有ポートでUSB3を無効にするオプションがあります。どちら側？知りません！
そのため、共有ポートは右側のものである可能性があります。 BIOSからUSB3を無効にして、両側の
dmesgの新しい出力と、lsusbの出力を確認します。
オプション2. BIOS/UEFIのアップグレード
新しいリリースがあります：

リリースノートにはUSBの問題のカウントが記載されていますが、最も興味深いのはこれです。
<2.19> UEFI: 2.19 / ECP: 1.08 - (Fix) Fixed an issue that might fail to boot the computer remotely. - (Fix) Fixed an issue where USB 3.0 device detection might fail when the device was attached via the USB 3.0 Hub and the USB 3.0 Mode option was set to Enabled in ThinkPad Setup.
